Don't forget their real-estate bubble, and entire empty cities meant for 1-2 million people.
My completely pragmatic brutal thoughts on China are as follows:
1. Hope for a double-dip recession/depression that sets off all of China's internal strains before they can create truly global military ones to try and compensate.
2. Set off said depression intentionally through a trade-war, embargo, 1:1 tit-for-tat trade pairty policy with China on the artificial Yuan, taxes, tariffs etc.
3. See if we can't somehow get China into a war with Russia/Putin. And stay out of it.
4. See if we can't somehow get China into a war with India/Pakistan (drawing in Russia). And stay out of it.
5. Keep going as we're going and hope that Cold War 2.0 with China ends more or less okay like CW 1.0 with the USSR did.
